The boxplots illustrate the following properties of your data:

·    The box represents the middle 50% of the data.

·    The line through the box represents the median for the sample.

·    The lines extending from the box represent the upper and lower 25% of the data (excluding outliers).

·    Outliers are represented by asterisks (*).
